A first terminal device has first data to be transmitted on a sidelink and has second data to be transmitted on an uplink. The first terminal device performs medium access control MAC protocol data unit PDU assembly on the first data or does not perform MAC PDU assembly on the first data based on a result of comparison between a transmission priority of the first data and a transmission priority of the second data.
Legal claims defining the scope of protection, as filed with the USPTO.
4. The method of claim 3, wherein the determination that the sidelink transmission opportunity is not discarded is made in response to the transmission priority of the first data being greater than the transmission priority of the second data.
5. The method of claim 3, wherein the transmission priority of the first data and the transmission priority of the second data each correspond to any one of the following: a proSe per-packet reliability (PPPR), proSe per-packet priority (PPPP), a 5G quality of service (QoS) identifier, or a QoS flow identifier (QFI).
6. The method of claim 1, wherein the periodic resources of the first terminal device are allocated by a network device.
7. The method of claim 1, wherein the specified quantity of sending times is obtained via radio resource control (RRC) dedicated signaling.
8. The method according to claim 1, wherein sending, using the transmission resource, the MAC PDU on the sidelink based on specified quantity of sending times comprises sending the MAC PDU on the sidelink without distinguishing between an initial transmission opportunity and a retransmission opportunity.
12. The apparatus according to claim 11, wherein the determination that the sidelink transmission opportunity is not discarded is made in response to the transmission priority of the first data being greater than the transmission priority of the second data.
13. The apparatus according to claim 11, wherein the transmission priority of the first data and the transmission priority of the second data each correspond to any one of the following: a proSe per-packet reliability (PPPR), proSe per-packet priority (PPPP), a 5G quality of service (QoS) identifier, or a QoS flow identifier (QFI).
14. The apparatus according to claim 9, wherein the periodic resources of the first terminal device are allocated by a network device.
15. The apparatus according to claim 9, wherein the specified quantity of sending times is obtained via radio resource control (RRC) dedicated signaling.
16. The apparatus according to claim 9, wherein sending the MAC PDU on the sidelink based on the specified quantity of sending times comprises sending the MAC PDU on the sidelink without distinguishing between an initial transmission opportunity and a retransmission opportunity.
20. The non-transitory computer readable medium according to claim 17, wherein sending the MAC PDU on the sidelink based on the specified quantity of sending times comprises sending the MAC PDU on the sidelink without distinguishing between an initial transmission opportunity and a retransmission opportunity.
